Hi Nilay, I used "$scons build/X86/gem5.fast RUBY=True PROTOCOL=MOESI_hammer " to compile gem5 and ran it with "$build/X86/m5.debug -d ruby-output configs/example/ruby_fs.py --kernel=x86_64-vmlinux-2.6.22.9.smp --script=configs/boot/mcf.rcS --cpu-type=detailed --ruby --checkpoint-dir=checkpoint-dir --take-checkpoints 10000000,100000"
I noticed that when I set cpu-type as detailed, it incurred segmentation fault. But if it was timing, it looked fine. But I am still testing it. Can you please tell me if x86+ruby supports detailed cpu-type? I will let you know if I make any progress.
